Better to just watch and listen for the full effect, as the imagery is integral.

One interesting twist to this film, which is often overlooked, is in the casting. Charles Bronson, the protagonist, up to that point almost always played the bad guy. Henry Fonda, who plays one of the truly great movie villains, almost always was the good guy. Leone's Westerns often blurred or obliterated the line between hero and villain, but that's the way it draws out in this one. It was a subtle move on the director's part, I suspect to add to the cognitive dissonance and ambiguities that often permeate his films.
